Escape analysis hates copy elision (2021)
Yesterday Lauri Vasama showed me this awesome Godbolt: struct S { static std::unique_ptr<S> make() noexcept; ~S(); static std::unique_ptr<S> factory() { std::unique_ptr<S> s = S::make(); return M(s); } }; void take_ownership(S*) noexcept; void test() { std::unique_ptr<S> p = S::factory()…

Learn Wayland by writing a GUI from scratch
Wayland is all the rage those days. Distributions left and right switch to it, many readers of my previous article on writing a X11 GUI from scratch in x86_64 assembly asked for a follow-up article about Wayland, and I now run Wayland on my desktop. So here we go, let's write a (very simple) GUI program with Wayland…

One game, by one man, on six platforms: The good, the bad and the ugly
Recently, Valve announced that Counter-Strike 2 would no longer support macOS . As a one-man indie developer who has released a game supporting macOS , I find myself at first surprised at Valve’s decision. But after looking back at my own journey of supporting six platforms, I feel I can understand Valve’s perspective.

How LSP could have been better
We talk about programming like it is about writing code, but the code ends up being less important than the architecture, and the architecture ends up being less important than social issues.

Bad Emacs defaults
I was working on a new installation where I didn’t have this in place yet and I kept trying to update a shell function, re-sourcing it but it never changed. Turns out it was loading from a backup~ of the same file.

How I Made a Heap Overflow in Curl
In association with the release of curl 8.4.0, we publish a security advisory and all the details for CVE-2023-38545. This problem is the worst security problem found in curl in a long time. We set it to severity HIGH. While the advisory contains all the necessary details. I figured I would use a few additional ……

Going faster by duplicating code
This function doesn't know the value being multiplied until it is called. The compiler (gcc, O2) emits a generic integer multiply instruction in its loop body.

Text showdown: Gap Buffers vs. Ropes
I have been working on a hobby project to reimagine the C core of Emacs in Rust. On this journey, I reached the point where I needed some way to represent the text of a buffer. The simplest approach is to just use a large string or array of lines. However these each suffer from poor performance as either the size or…

My personal C coding style as of late 2023
This has been a ground-breaking year for my C skills, and paradigm shifts in my technique has provoked me to reconsider my habits and coding style. It’s been my largest personal style change in years, so I’ve decided to take a snapshot of its current state and my reasoning. These changes have produced significant…

Forty years of programming
I am about to turn forty-six. This means I have been programming for forty years, half of them professionally. During most of that time, I used a "standard" setup with 104 keyboard, a flat mouse, and a sitting desk.

Speeding up the JavaScript ecosystem – The barrel file debacle
Many projects are littered with files that just re-export other files. These so called "barrel files" are one of the key reasons why JavaScript tooling is slow in bigger projects.

Calling Rust from Python
I recently watched GOTO conferences' talk Calling Functions Across Languages by Richard Feldman. I’m afraid I have to disagree with using the term 'language' in this context. It’s a no-brainer to call Java from Kotlin or Scala or to call Java from Kotlin. Hence, in the rest, I’ll use 'stack'.

Debian is a large, complex operating system, and a huge open source project. It's thirty years old now. To many people, some of its aspects are weird. Most such things have a good reason, but it can be hard to find out what it is. This is an attempt to answer some such questions, without being a detailed history of…
